Question

27:[26+(6×a-21):9]+1=2va rog frumos răspunsul sa fie dasfasurat.multumesc

Answer 1

27:[26+(6×a-21):9]+1=2
27:[26+(6×a-21):9] = 2-1
27:[26+(6×a-21):9] = 1
[26+(6×a-21):9] = 27:1
26+(6×a-21):9 = 27
(6×a-21):9 = 27-26
(6×a-21):9 = 1
6×a-21 = 1×9
6×a-21 = 9
6×a = 9+21
6×a = 30
a = 30:6
a = 5
